Canon Issues Product Advisory for EOS 5D Mirror Separation Issue

When
the Canon EOS 5D was first released in 2005, we were impressed that
Canon was offering a Digital SLR using a larger 35mm Film Size Sensor
that was the most affordable full frame camera model to date, while
still including Professional Level features at a lower price point
compared to other cameras using a sensor that large.

The
EOS 5D included a newly developed shutter mechanism that was designed
to be durable and meet the demanding requirements of a full frame
sensor in a relatively compact body style at the time of it's
introduction. The shutter mechanism supports speeds as fast as
1/8000 second and uses a quick return half mirror design that
prevents any mirror cut off with EF 600mm f/4 or shorter focal length
lenses.

But,
now, almost 10 years after its release in August 2005, Canon has
noticed a problem with the adhesive used to connect the mirror, and
has issued a Product Advisory indicating that the main mirror may
detach in rare instances due to the strength of the adhesive
deteriorating.

If
you have an affected camera and the main mirror has detached, you
will no longer be able to see images through the viewfinder.

Canon
USA says it will repair the mirror portion of the affected cameras at
no charge. As you can see from the photo below, they will attach
reinforcement parts to the left and right sides of the mirror to
accomplish this repair.

If
you have an EOS 5D with this problem, it would be a good idea to get
it fixed soon, since the original EOS 5D service period will end on
September 30, 2015 (and repair centers may not be taking cameras
after that date).
